AN INVESTIGATION OF RAIL-TO-CONCRETE FASTENERS

Prestressed concrete ties are being increasingly used. This investigation deals with rail-to-concrete ties, bridge decks, and tunnel linings. For spring-clip fasteners in concrete ties, three methods of electrical insulation are studied. These fasteners were subjected to tie-wear tests, longitudinal-slip tests and electrical-resistance tests. The anchors used were also subjected to pullout tests. For fasteners in bridges and tunnels, three different fasteners were tested under repeated loading. In addition, the "second-cast" method of construction was studied.
